TELEPHONE,

SPECIFICATION forming part of Letters Patent No. 626,629, dated June 6, 1899.

Application filed April 13, 1897. Serial No. 631,971. (No model.)

Of course it will be understood that while I To all whom it may concern:

county of Philadelphia, in the State of Pennsylvania, have invented a certain new and the following is a true and exact description, reference being had to the accompanying drawings, which form a part thereof.

Our invention relates to improvements in the construction and mode of operation of telephones, and particularly of switches used in connection with a telephone system, our object being to combine with a telephone instrument or instruments and with a telephone and call circuits a system of rotative switches moving with the telephone, which has also a rotative movement from a point of rest to a point of use and so that by simply turning the telephone instrument upon a pivot it will close and open the various circuits at the proper time.

The nature of ourimprovements will be best understood as described in connection with the drawings, in which they are illustrated, and in which Figure 1 is a front view of a box or case containing our arrangement of telephone and switches, taken as on the section-line z z of Fig. 2. Fig. 2 is a side elevation taken on the section-line so as of Fig. 1. Fig. 3 is a transverse section taken on the section-line y y of Fig. 1. Fig. 4. is a side elevation of the switching-drum and its connections, taken on the opposite side to that shown in Fig. 2. Fig. 5 is a perspective view of the case and telephone, the telephone being turned outward in position for use. Figs. 6, 7, and 8 are diagrammatic representations of two telephone-stations, showing the operation of our device. Thus Fig. 6 represents the condition of the circuits when both telephones are turned up in position of rest, Fig. 7 represents the condition of the circuits when the one telephone that in station T-is turned to position to call the telephone in the station V, and Fig. 8 represents the condition of the circuits when the telephones in stationsT and V are both turned out of the casein position for use.

we show the two stations our invention is adapted for use on any telephone system by the intervention of the usual switchboard or analogous device.

A indicates the casing, which, as shown, is a rectangular box having a door A, hinged at a.

B is a standard secured within the casing, having a perforated flat side extension B.

C is a support for the telephone instruments, slotted so as to have arms 0, between which the extension B can be passed, while a pin F will pivot the standard B and the support 0 together. The desired amount of friction to insure that the support 0 will remain in whatever position it may be placed is 1 secured by a nut F, screwing on a threaded end of the pivot-pin F, and, as shown, the other end of the pivot-pin F is secured so as to make a positive engagement with one arm O of the support 0, and the drum G, to be hereinafter described, is firmly secured to the pin F. As shown, the support 0 sustains both the transmitter D and the receiver E, the bent tubular arm (3 extending from the receiver,

upon which is placed a sleeve 0 within which sleeve also fits the tubular arm 0 of the receiver. This arrangement permits the adjustment of the receiver to different distances from the transmitter, thus adapting the instrument to the use of different operators; but while we prefer to secure both the transmitter and receiver together and to the same support 0, it will be obvious that either may be secured to the pivot-support O,while the,

other may be independently supported, and

where in the claims we refer to the telephone as an element of the combinations designated we wish to be understood as including the pivoted arrangement of either a receiver or transmitter, or both.

G is a drum, of vulcanite or other non-con ducting surfaces, secured, as already stated, to the pivot-pin F, and, as shown, we place upon one side of this drum a plate H, cut away at one place, as indicated at h, while upon the other side of the drum We place a plate I, also cut away atone portion, as indicated at 11. Connected with one edge of the plate H and extending over the face of the drum is ametallic plate, H, and connected with the edge of the plate I and also extending over the'face of the drum are the metallic plates 1' and 1 while secured upon the face of the drum, but not in contact with either plate H or I, is a metallic plate J.

K and K are spring-contacts connecting, respectively, with the wires 5 and 12, to be hereinafter described, and so situated with respect to the face of the drum G that they will simultaneously make contact with the plate H when the drum is rotated to a position to bring the said plate beneath them.

K and K are spring-contacts connected with the wires 13 and o and both resting against the side of the drum in position to make contact with the plate H, said plate being cut away at h in such wise as to interrupt the contact which the spring K makes with the plate in one position to which the drum is rotatable-viz. that in which the drum and the telephone instrument are turned in the construction indicated in the drawings to a position at about ninety degrees to that inwhich theparts are represented in Figs. 1 to 4.

K and K are spring-contacts connected with the wires 14 and 10, so placed with respect to each other that when the telephone and drum are turned to the position of about forty-five degrees to that shown in Figs. 1 to t they will both contact with the metallic plate J, the plates 1 and I being so disposed and arranged on the drum that in the position indicated in Figs. 1 to 4: the spring-contact K will be in contact with the plate while a turning down of the telephone and drum to the extent of about ninety degrees will bring the contact K into contact with the plate I. The seventh spring-contact, that indicated at K and which is connected with the wire 9, is so placed as to rest against the plate I, the recess tin said plate being so arranged as to interrupt the contact between the spring K 'and the plate I- at the point in the movement of the drum when the plate J is in contact with the springs K and K Lind'icates an induction-coil, and M a callbel l Referring to the diagrams, 1 and 7 indicate the line-Wires connecting with the main source of electrical energy, (indicated at N.

0 indicates a call-battery situated in the line 15; but it will be understood that in place of such a battery any generator or series of generators adapted to give either a constant or intermittent current to actuate the call device may be used.

Referring again to the diagrams, we have ind'icatedin each one two telephone-stations, marked, respectively, T and V,)' each connecting with the line-wires 1 and 7, respectively, through wires 2 and 6. As shown, the wires 2 pass to the transmitter D, and

thence continue as wire 4 through the primary coil of an induction-coil L, passing thence through wire to the spring-contact K.

' plate H, spring K and wire 6 to the linewire 7.

This position of the drum is shown in Fig. 8 of the drawings. The induced or secondary current incident to the closing of the primary circuit passes through wire 9 to spring-contact K" and thence to plate I and plate I, which when the drum is turned to the position to close the primary circuit is in contact with spring K through which and line 10 the current passes to the line 11, and

thence to line 10 of the other station, which, the drum G- being in the same position as the first station, communicates through spring K and plates 1 and I with spring K, and thence through wires 9 and S withthe receiver E, the circuit being continued through line 12, the spring K, plates H and H, spring K wire 6, wire 7, wire 6 of the other station.

tion, spring K plates H and H, spring K, and wire 12 to the receiver E of the first sta- It will be noticed that in the position iindicated in Fig. 8 the spring K is out of contact with the plate H, resting against the face of the drum at h, while the spring K also rests against the non-conducting face of the drum, and it will also be noticed that in the position of restthat indicated in Figs. 1 to 4 and Fig. 6 of the diagramsthe spring- ;contacts K and K and the spring-contact K prest against the non-conducting surface of the drum, while the springs K and K are both in contact with plateIl, and the spring 1 K in contact with plate I.

K is in contact with plate 1 and the spring By turning the drum to about forty-five degrees-that is, a position intermediate between that indicated Sin Figs. 1 to 4 and that indicated in Fig. 5 the drum in station T (see Fig. 7)-is turned i to a positionin which the spring-contacts K and K rest against the metallic plate J. This couples the battery-wire 15 with the wire 11 3 through the wires 14 and 10, and the drum in station V, remaining in the position indicated ji-n Fig. 6, the current passes from wire 11 Ithrough wire 10, spring K plates 1 and I, iwire 9 to wire 13, ringing the hell or actuating any other signal connected with said line drum to the position shown in Fig. 8, and the j operator in station T also-drawing down the itelephone to operative position the two stations will be placed in communication.

From the above description it will be seen 3 that we have shown the usual telephone-cm cuit, distant-call circuit, and local-call circuit, each local-call circuit of one station being a part of the distant-call circuit of the other station. Both the distant and local call circuits may in some cases be dispensed with, and of course in such case the corresponding switches upon the rotating drum may also be dispensed with and only those switches which open and close the telephone circuit employed. Again, it is sometimes desirable to equip one station so that another station or stations may be called by it, but without providing for a call to the first station. In this case the local-call circuit can be omitted and the corresponding switches also omitted.

It will be observed that when the telephone instruments are turned into position to be used, and by reason of the switch connections the circuits are simultaneously put into condition for use, the movable support, with the transmitterand receiver, will project from the box. This renders it impossible for the user to inadvertently leave the circuit in such a condition that the station could not be called, for unless he is sufiiciently careless to leave the entire box open he is forced to restore the circuits. The support carrying the instruments must be turned up within the box before the door can be closed, and of course in being so turned up the switch is likewise turned without any'particular thought being given to it by the user.

Having now described our invention, what we claim as new, and desire to secure by Letters Patent, is- I 1. A telephone-substation apparatus comprising the followinginstru mentalities: a casin g, a fixed support permanently secured upon the casing, a movable support, a receiver and transmitter carried upon said movable support in the proper relative positions which they should occupy when in use, a pivotal connection between the fixed and movable supports, an insulated drum orcylinder secured to the movable support and .having its axis coincident with the axis of the pivotal connection, one or more conducting-segments secured upon the periphery of the cylinder, and fixed contact-springs forming terminals for the telephone-circuits, carried-upon the fixed support and having their extremities resting upon the surface of the cylinder, substantially as described.

2. A telephone-substation apparatus comprising in combination a box or casing having automatically completed, but the movable support must be turned to properly alter said circuits before the box-door can be closed, substantially as described.

3. A telephone-substation apparatus comprising in combination a box or casing having a door, a fixed support within said casing, a movable support carrying a receiver and transmitter and pivoted at one extremity to said fixed support, a rotary switch connected to the movable support to be actuated in its motion and thereby change the telephone-air cuits, the movable support being adapted to project forwardly and without the box or casing when turned into the position of use, and when in such position constituting an impediment to the closure of the box-door, substantially as described.
